"if i sing one of my self penned songs ,i am no longer a singer of traditional songs ,but as soon as i sing a traditional song i become one again, if i decide to sing a cw song i become a cw singer[even if i dont do it very well]likewise if i choose to sing a blues i become a blues singer [even if i am not a good one] "

That's all perfectly true, but at the risk of repeating what I said a few posts ago, how is that remotely helpful?
